17-85mm lens error 01 on 550D, works on 450D

Hi,

I have 4.5 years old 550D and even older 17-85. Now this specific combination fails with error 001 - communication between lens and camera.

1. The same body works with my 24-105L and Sigma 18-200 (borrowed from friend for testing).

2. The same lens (17-85) works on another body - ~6 years old 450D (borrowed from friend for testing).

Only the combination 550D + 17-85 doesn't work.

I tried to clean contacts of 17-85 but it didn't help.

Any ideas ?

Alex.

P.S.

I tried the following steps found somewhere:

Turn off camera
Remove lens
Turn on camera and take two pictures with no lens
Turn off camera
Replace lens without turning all the way into the lock position
Turn on camera and take one picture
Turn off camera
Turn lens the rest of the way to its locked position
Turn on camera and take picture [error 01 should be gone]

This sequence works, actually the same effect is achieved with just shooting one picture without lens, and reattaching the lens.

It helps for several shots, then error reappears.
